What is BMI?

BMI stands for Body Mass Index. It is a numerical value that is derived from a person's weight and height. It is used to assess whether a person has a healthy body weight for their height. BMI is important to measure because it provides an indication of whether a person is underweight, normal weight, overweight, or obese. It is a useful tool for identifying potential health risks associated with weight, such as cardiovascular diseases, diabetes, and certain types of cancers. It is widely used by healthcare professionals and researchers to assess population health and to guide recommendations for weight management and overall health.

How The BMI Calculator Works?

Given that the height is 5 feet and 9 inches, and the weight is 189 pounds, you can calculate your BMI by

  • entering "5" in the box labeled "height, feet,"

  • entering "9" in the box labeled "height, inches," and

  • entering "189" in the box labeled "weight, pounds."

  • Then, click on the checkmark to compute your BMI.

How to Calculate Body Mass Index (BMI) Using BMI Calculator

To calculate BMI (Body Mass Index), you can use the following formula:

  • BMI = weight (in kilograms) / height^2 (in meters)

Steps to calculate your BMI:

  • Measure your weight in kilograms. If your weight is in pounds, you can convert it to kilograms by dividing it by 2.2046.

  • Measure your height in meters. If your height is in inches, you can convert it to meters by dividing it by 39.37. If your height is in feet and inches, you can convert it to meters by multiplying the number of feet by 0.3048 and adding it to the number of inches multiplied by 0.0254.

  • Square your height in meters (multiply it by itself).

  • Divide your weight in kilograms by the squared height.

The resulting number is your BMI. It indicates whether you are underweight, normal weight, overweight, or obese based on the following categories:

BMI Indexes

  • BMI less than 18.5: Underweight

  • BMI between 18.5 and 24.9: Normal weight

  • BMI between 25 and 29.9: Overweight

  • BMI greater than or equal to 30: Obese

Remember that BMI is a general indicator and doesn't take into account factors such as muscle mass, so it may not be the most accurate measurement of body fatness for athletes, bodybuilders, and individuals with a high muscle mass.

BMI Calculator Usage

BMI (Body Mass Index) calculator allows individuals to determine their body mass index by taking into account their height and weight. BMI is a number calculated based on a person's weight and height, providing an indication of whether a person's weight is healthy for their height.

This tool is commonly used to assess the level of obesity or underweightness within a population. By inputting one's height and weight into the BMI calculator, individuals can get an estimate of their BMI and determine whether they fall under the underweight, normal weight, overweight, or obese category according to established ranges. This information can be beneficial for individuals who are seeking to monitor and manage their weight for overall health and well-being.
